Normally, mind control is Thaumaturgy. Look under Psychomancy specifically. For Evocation mind control, I'd suggest most of it's probably a Block against specific actions...though a weapon inflicting Mental Stress might make some sense as well. In terms of Element, Mental Effects are clearly under Spirit, as far as Evocation goes.
As for illusions, there are two ways to do them: As a mental effect (breaks the Laws), or as a construct of light and sound (doesn't break the Laws), either seems likely to use Spirit, though Air might be involved in the second one as well. From a mechanics perspective they're more maneuvers, or a special kind of block (ala Veils) than they are an attack.
