Electricity is fine, then.
The ability as written is ok, but I think it should probably specify that a grappled/grappling opponent takes electricity damage each round (sort of like a combination of barbed defense and impale from the barbed devil). And we need a table for the damage. I guess 1d6 should be the damage for the Medium quasi-elemental with usual size category advancement. Sound ok to you?
Electricity (Ex): A lightning quasi-elemental is composed completely of electricity; therefore any creature touched or touching it takes electricity damage as specified in the table, and an opponent grappling or grappled by the quasi-elemental takes damage each round it remains in the grapple. An opponent grasping or wearing conductive material (metal weapon, armor, and so on) that comes into contact with a lightning quasi-elemental (including by making a successful melee attack against it) takes damage also.
<Table>
The basic mechanics are OK, but the original wording is rather messy, plus it doesn't need the "A lightning quasi-elemental is composed completely of electricity; therefore" explanation.
I'm not that bothered about adding a note on electrifying-in-a-grapple, but I guess it doesn't hurt (provided you have enough electricity resistance).
As for the damage, I'm thinking it should use the same electricity damage as its slam attacks - that is where the slam's electricity damage comes from, after all.
I'm also considering adopting a bit of the wording from the 3.5 Fire Elemental's Burn Special Ability.
SRD said:Burn (Ex): A fire elemental’s slam attack deals bludgeoning damage plus fire damage from the elemental’s flaming body. Those hit by a fire elemental’s slam attack also must succeed on a Reflex save or catch on fire. The flame burns for 1d4 rounds. The save DC varies with the elemental’s size (see table). A burning creature can take a move action to put out the flame. The save DC is Constitution-based.
Creatures hitting a fire elemental with natural weapons or unarmed attacks take fire damage as though hit by the elemental’s attack, and also catch on fire unless they succeed on a Reflex save.
How about:
Electricity (Ex): A lightning quasi-elemental’s slam attack deals bludgeoning damage plus electricity damage from the elemental’s electrical body. The quasi-elemental can also inflict electricity damage with a melee touch attack or a grapple check (it need not win the grapple check to deal damage, mere contact is enough).
Creatures hitting a lightning quasi-elemental with natural weapons, unarmed attacks or weapons made of conducting materials (i.e. metal swords) take electricity damage as though hit by the quasi-elemental’s attack.
