seeing through the eyes of scriptures
Lord Vamanadeve is best worshipped by full Nirjala fasting as explained in Hari Bhakti Vilasa, and chanting 64 rounds, and reading the pastimes in Srimad Bhagavatam in relation to Him
SB 6.8.13: May the Lord, who assumes the body of a great fish, protect me in the water from the fierce animals that are associates of the demigod Varuṇa. By expanding His illusory energy, the Lord assumed the form of the dwarf Vāmana. May Vāmana protect me on the land. Since the gigantic form of the Lord, Viśvarūpa, conquers the three worlds, may He protect me in the sky.

One may perform the puja over a kumbha, install a murti or worship Vamana in a salagram, offering sixteen upacaras, a bamboo danda, jala mala, upavita, paduka and umbrella, the articles held by the brahmacari, Vamana deva.
Asana, padyam, arghyam, acamaniyam, madhuparka, bath, cloth, sacred thread, ornaments, gandha, flowers, incense, lamps, naivedyam, betel nut and pranamas may also be offered.
Special arghya (barley, kusa, tulasi, yoghurt, flowers, etc.) prayer is as follows:
vamanaya namas tubhyam kranta tribhuvanaya ca
grhanarghyam maya dattvam vamanaya namo'stu te
The next day one may feed the brahmanas, give gifts and break the fast.
Conerning this festival Srila Prabhupada has said:
Dress a (little boy), give him a special raised seat, offer him the best prasada. Everyone should offer their respects by touching his feet.
ya idaṁ paramaṁ guhyaṁ
bhaktiṁ mayi parāṁ kṛtvā
mām evaiṣyaty asaṁśayaḥ
For one who explains the supreme secret to the devotees, devotional service is guaranteed, and at the end he will come back to Me.
The Lord appeared in His original form, with ornaments and weapons in His hands. Although this ever-existing form is not visible in the material world, He nonetheless appeared in this form. Then, in the presence of His father and mother, He assumed the form of Vāmana, a brāhmaṇa-dwarf, a brahmacārī, just like a theatrical actor
purport by Srila Prabhupada
The word naṭaḥ is significant. An actor changes dress to play different parts, but is always the same man. Similarly, as described in the Brahma-saṁhitā (5.33, 39), the Lord assumes many thousands and millions offorms (advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣam). He is always present with innumerable incarnations (rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan nānāvatāram akarod bhuvaneṣu kintu [Bs. 5.39]). Nonetheless, although He appears in various incarnations, they are not different from one another. He is the same person, with the same potency, the same eternity and the same spiritual existence, but He can simultaneously assume various forms. When Vāmanadeva appeared from the womb of His mother, He appeared in the form of Nārāyaṇa, with four hands equipped with the necessary symbolic weapons, and then immediately transformed Himself into a brahmacārī (vaṭu). This means that His body is not material. One who thinks that the Supreme Lord assumes a material body is not intelligent. He has to learn more about the Lord’s position. As confirmed in Bhagavad-gītā (4.9), janma karma ca me divyam evaṁ yo vetti tattvataḥ. One has to understand the transcendental appearance of the Lord in His original transcendental body (sac-cid-ānanda-vigraha [Bs. 5.1]).
taṁ vaṭuṁ vāmanaṁ dṛṣṭvā
karmāṇi kārayām āsuḥ
When the great sages saw the Lord as the brahmacārī-dwarfVāmana, they were certainly very pleased. Thus they placed before them Kaśyapa Muni, the Prajāpati, and performed all the ritualistic ceremonies, such as the birthday ceremony.
According to Vedic civilization, when a child is born in the family of abrāhmaṇa, the birthday ceremony, known as jāta-karma, is first performed, and then other ceremonies are also gradually performed. But when this vāmana-rūpa appeared in the form of a vaṭu, or brahmacārī, His sacred thread ceremony was also performed immediately.
LORD Vamanadev is given a brahmin initiation at His transcendental birth cermony and donations offered to him,being the "Supreme Brahmana"
SB 8.18.14: At the sacred thread ceremony of Vāmanadeva, the sun-god personally uttered the Gāyatrī mantra, Bṛhaspatioffered the sacred thread, and Kaśyapa Muni offered a straw belt.
SB 8.18.15: Mother earth gave Him a deerskin, and the demigod of the moon, who is the king of the forest, gave Him abrahma-daṇḍa [the rod of a brahmacārī]. His mother, Aditi, gave Him cloth for underwear, and the deity presiding over the heavenly kingdom offered Him an umbrella.
SB 8.18.16: O King, Lord Brahmā offered a waterpot to the inexhaustible Supreme Personality of Godhead, the seven sages offered Him kuśa grass, and mother Sarasvatī gave Him a string of Rudrākṣa beads.
SB 8.18.17: When Vāmanadeva had thus been given the sacred thread, Kuvera, King of the Yakṣas, gave Him a pot for begging alms, and mother Bhagavatī, the wife of Lord Śiva and most chaste mother of the entire universe, gave Him His first alms.
SB 8.18.18: Having thus been welcomed by everyone, Lord Vāmanadeva, the best of the brahmacārīs, exhibited His Brahmaneffulgence. Thus He surpassed in beauty that entire assembly, which was filled with great saintly brāhmaṇas
In the Garga Samhita it is mentioned how the demigods went to Goloka Vrindavan in the Varaha Kalpa and asked Krsna to come to earth, one Gopi asked them from which univers they came from,well let me look it up" it is just much transcendental fun not to share"

the demigods went to Ksirodaksaiy Visni in that Kalpa and he took them to Goloka Vrindavan, so our univers is famous even in Goloka Vrindavan because Lord Vamanadevs lotus toe broke the layers of matter and the Ganga came thus to this univers.
