Her E's damage per attack is: her base attack damage + her attack damage added from items + Righteous Fury's base magic damage bonus + Righteous Fury's magic damage bonus added from 30% of her total ability power.

As the magic damage is added per attack, getting more attack speed increases how much damage Righteous Fury will do. This magic damage is not affected from critical strikes and improved critical strike damage.

Basically, just like Kog'Maw's Bio-Arcane Barrage in terms of damage types. Attack damage + magic damage from the ability.
