It's easy if you have any existing trad skills but the following is useful:
Learn how to use a guide plate belay device, attach yourself (at the top of each pitch) to something solid and convenient (usually a stemple) and attach the guideplate to a higher anchor (typically the peg/bolt anchoring the wire or another stemple) using a sling and direct belay off of that. This is much easier in these circumstances than a belay off your belt.
Position your belay so that the 2nd has a good landing place below you (typically the bolt/peg holding the wire one section below you, ideally with stemples or a ledge) so they can belay you without having to share your stance but so that they are within reach to pass you any anchors.
QDs work as runners but often the pegs (holding the wire) are too thick for the carabiners to clip so it is handy to carry some slings and carabiners you can loop over or larks foot to the pegs (use these rather than the wires on anything other than vertical so the runners don't slide along the cable when needed in anger, on vertical pitches you don't really need runners because you are above the second and their VF kit keeps them close to the wall. Your own VF kit protects you as well as the lead rope would).
Each carry the usual resting QDs and a sling /screwgate larks footed to your belay point to make belays.
Take gloves - the iron work can be very cold.
Be prepared to aid any icy sections - short days, the cold and possible difficult descents favours progress over purity.
Know how to retreat if the ice is very bad - especially if the VF is a mountain affair - it is likely to get worse as you ascend. Take headtorches.
Generally though it's pretty much the same deal as the summer only colder!
