Rule of spellvam/lifesteal:

Autoattack damage procs lifesteal.

ALL abilities, whatever their damage type and application method, apply spellvamp. Except in one case: ONLY abilities that apply on-hit effects proc lifesteal.

Yoric's Q enhances his autoattack to deal physical damage, but it's not an ability that procs on-hit effects and is applied by an autoattack, it's an ability that deals extra damage on his next autoattack target the next time he autoattacks, so it procs spellvamp.
