Assalaamu Alaikum Wr Wb,
wazifa alone is done silently with moving lips and reciting it aloud while you are doing it alone is makruh.
start with the niyyah then aoozu and bismillah:
1. surah al-fatiha and in the end aameen
2. 30 times astaghfirullahal azeemal lazi la ilaha illa huwal hayyul qayyum
3. 50 times salatul fatih
4. 1 time subhana rabbika rabbil izzati amma yaseefun wa salamun alal mursaleen wal hamdulillahi rabbil alameen
5. 100 times la ilaha ilallah and on 100th add Sayyedina Muhammadur Rasoolullah Alaihi Salamullah
6. 12 times johratul kamaal, in the last johratul kamaal raise your hands like the dua, with hands raised add innalaha wa malaikatahu... till the end of the ayah. then Sallallahu Alaihi Wa Ala Alihi WaSahbihi Wassallimu Tasleema then again subhana rabbika rabbil izzati... till the end.... then wipe your hands on the face like the dua... then you can perform proper dua...
you do have to spread a white sheet if its available but its not a hurdle.
hope this helps.
wassalaam
