Which lager you want to brew? AG, PM, or extract? If you are a new brewer and don't have the capability to strigently control temps from 68-32F, then I would avoid doing a lager - For now. But if you did want to do a lager and can control temps, I would do a simple Munich Helles or an Oktoberfest. The nice thing about the Helles is it is going to work better using dry W34/70 yeast. Granted you could do the Ofest with that yeast, but I would suggest using a liquid yeast for that though. If this is your first beer, I would really suggest you do an ale which is far more forgiving and will make it a little easier to get a good beer on the first try... in that case, if you like lighter beers like most Americans and Canadians are used to, then I would suggest doing a Kolsch.
