It can indeed apply both spellvamp and on-hit effects, however not to the same part of the attack.

Drunken Rage is an auto attack modifier which causes your next auto attack (this auto attack deals physical damage and counts exactly as an auto attack in every way) to deal bonus magic damage (this magic damage is counted as a spell and you can spellvamp from it or rylai's, etc.)
