Water Ice (*Probably)
I've always imagined the formation of the solar system being: "Here's a group of gases - start clumping together and see what happens.". If this is all there is too it, your question should be pretty simple to answer:
I believe it would follow that hydro carbons would be more common, and water would be less common. Those bodies would have more methane, probably oceans of the stuff.
At a stretch, you may even get naturally occurring seas of methanol (Carbon monoxide + hydrogen + high temp + high pressure + one of many catalysts = methanol).
Equally as much of a stretch, replace carbon monoxide with nitrogen (and the choice of catalyst with a fickle temperature range), you get ammonia, however the strong triple-bond of nitrogen makes it a very slow reaction. To quote wikipedia: basically inert.. It would seem unlikely that you'll get a lot of ammonia.
Methane and Methanol would be my answer in this case.
Earth's protoplanetary disk was too hot to form water with the earth, and where that water came from is an open question - all the hyptopheses linked there require some form of bombardment. Maybe it came from outside the solar system, maybe it formed at the belt, and Jupiter chucked it at us, we don't know.
Research linked to from https://en.wikipedia.org/wiki/Interstellar_ice, suggests that up to 50% of the water in the solar system predates it. Tiny grains of amorphous water and methanol exist in the intersteller medium, apparently becoming crystalline in the presence of a star. These ice crystals would form into ice balls, and eventually become comets, which, during the late stages of solar system formation, bombard it with water.
Assuming this is where the solar systems water came from - These comets would contribute water to the solar system regardless of the oxygen / carbon ratio. You'd still get Ice in the far reaches of the solar system.
