They do. The item is not core on Yorick just because of the mana regen, it gives his ghouls some actual damage. Do note that when farming, it is wise to toggle Muramana off, or you'll see Yorick's mana go away REALLY fast (okay, faster than usual).

When any of Yorick's Ghouls attacks a target it counts as if Yorick himself attacked it (take a look at the passive's Ability Details in this page). They apply Elder Lizard too, so you could actually jungle Yorick if you so desire and get some decent use out of Elder Lizard.
