I've rounded up all the usual suspects.

Origins of the Mages Guild
Mannimarco revisited
Mannimarco:light and dark
Midas Magic
Wizard robe, beard and hat mods

But I'd love to find some more quest mods for mages. Any suggestions?

Integration is the main one. it involves a lot of magic, riddle solving, socialization, being able to find multiple solutions to things, scholarly stuff, lot's of lore learning, etc. and it does all of that in fun, unique, interesting ways.... because we all know that mages don't care about fetching things or clearing dungeons. It's all about the knowledge, power, politics, experimenting, and other cerebral exercises.

What else is there.... uhhhh
*after checking some stuff to refresh my memory*
Alyeid Steps
Sentient weapons? (I dunno having souls trapped in a weapon seems like a mage type thing)
Adash - City of Magic (haven't played this one, basing it purely off the name...)
