Wa 'alaikum salam wr wb, I don't think that any 'amal is specifically prescribed on this night. I would advise fasting on this day because after Ramadan, it was this month in which Nabi(saws) fasted the most. This day also comes in the ayyaam-e-beed which is the 13th to 15th of every month. Some Salah, some Dhikr, some Du'a and Istighfaar should be enough, Insha-Allah. Everything should be done at an individual level. Wasalaam.
