Padmavati Devi is considered a Yakshini (attendant goddess) of Bhagwan Parshvanath in Jainism. The exact pooja vidhi (sequence) can vary by temple and by whether the tradition is Digambara or Shwetambara. A simple, commonly followed sequence seen in Jain temples is:

• Pranama and avahana: Invite Padmavati Devi and, if used in the temple, Parshvanath Bhagwan. (bhavna of devotion.)
• Shuddhi and aaroha: Purify the altar area and place a clean cloth or altar cloth; keep Kalash with water at the center if used.
• Kalash sthapna and deepa: Set a small lamp (diya) and, if available, a kalash with water and mango leaves.
• Abhishek and alankar: Give a light bath to Padmavati’s image/idol with water or panchamrit, followed by sandalwood paste, kumkum, and fresh flowers.
• Archana and stuti: Offer flowers, garlands, and recite Padmavati stuti or namas (devotional verses) honoring her qualities of auspiciousness, prosperity, and protection.
• Naivedya and offerings: Present prasad such as fruits, sweets, and a small plate of holy rice/puffed rice as naivedya; offer tulsi leaves if desired.
• Mantra japa and community arati: Chant Padmavati mantras (as advised by the temple) and perform aarti with a lamp before the deity.
• Prasad distribution and closure: Conclude with prasad distribution to participants and a final bhavna for blessings.

Differences to note

• Digambar vs. Shwetambar: Padmavati is commonly kept as the Padmavati Yakshini of Parshvanath; the placement can differ. In many Digambar temples, Padmavati is placed on the right side of Parshvanath (devotee’s left). In some temples or traditions, arrangements may vary. You can read the Digambar placement note here.

If you want, I can tailor the sequence to a specific temple tradition (Digambar or Shwetambar) or provide a concise, temple-specific vidhi you found locally.
