give it an oil change before you put it away and make sure its clean and dry.
to be honest, if its in the uk and ireland its going to get a bit damp unfortunately so just try and make sure its aired as much as possible. stick one of those £1 de-humidifier things in the car to keep any possible mould away.
everyone does things differently. if its only a year, its not so bad. i would be tempted not to touch it at all during the winter months, but get someone to give it a few good runs out in the summer if you can. failing that, just getting it out of the garage and sarting her up and making sure it gets warmed through. in the winter this can do more harm than good due to the water produced from the exhaust.
make sure the fuel tank is about half full at least.
