A good portion of LaVey's Satanic bible is dedicated to (very silly) spells and invokation rituals. I don't think LaVey's form of Satanism was ever really popular in black metal circles though. There's something about it in Lords of Chaos but it's been too long since I read it to remember what exactly.
Dissection are the only currently active band I can think of at the moment. I used to think that was atleast somewhat in jest but after seeing that recent Death Metal Murders documentary I noticed they were actually deadly serious about it. So when you read ramblings like these on Blabbermouth:

...and when they say things like their new album is "a work of sonic black magic, actively channelling the anti-cosmic current 218.", they aren't joking. Weirdos.
