There is no single required 'ritual' for Laylat al-Qadr beyond sincere worship, so the Sunnah simply intensifies the acts already legislated: standing in voluntary night prayer (qiyam al-layl / tarawih), reciting and reflecting on the Qur'an, repeating dhikr and istighfar, and making du'a — especially the du'a the Prophet ﷺ taught Aisha. Many companions and later scholars also increased charity in these nights, in keeping with the Prophet's ﷺ own generosity being at its peak in Ramadan.

If you are only able to do a little, do a little consistently rather than nothing at all: even a short qiyam, a few pages of Qur'an, and the forgiveness du'a repeated sincerely fulfil the 'iman and ihtisab' the hadith describes. Those able to take time off work or increase their solitude may also perform i'tikaf (seclusion in the mosque) in the last ten nights, following the Prophet's ﷺ own practice.
