It's not the recipe that's the trick with lagers, it all about fermentation temperature and how you handle the yeast. For instance, a very nice Helles can by made by using a little carapils and the rest pilsner malt with maybe 20 IBUs worth of noble hops, no aroma or flavor hops. A great dunkel is mostly Munich malt with maybe a little Meloidin malt and a little carafa for color, same hops as the Helles. I agree with Benson that Octoberfest is really a great beer but for some reason, it is pretty tricky to get one just right, I will however keep trying. Most general homebrewing books will have a few lager recipes, there really is no big mystery about lagers but they are a little more trouble than ales.
Anyway, you want to ferment at 48-50F to get the clean fermentation profile you are looking for. I make up a yeast starter of almost a gallon (or use the yeast off a previous batch) for a 5 gallon batch. You do not want to stress the yeast at all otherwise it will start throwing off those nasty by-products we want to keep out of our clean lagers. I have a stir plate that I use for making yeast starters and it is really a handy toy for growing up a big, healthy starters. Aeroate the hell out of your wort when you pitch the yeast and also always rack the wort off the trub before pitching. I almost always do at least a single decoction for German lagers, mostly to try and get the almost creamy mouthfeel the good examples all display but I understand some on this board would argue that this is not necessary.
I think that once you get your processes down making lagers, you will find that all your beers will benefit. Many ales, especially the darker varieties, are more forgiving of technique issues than are most lagers. You will find that Belgian styles as well as German wheat beers are also pretty sensitive to yeast handling, certainly more so than are British or American ales for instance and experience making lagers will help you with those also. Anyhow, welcome to the dark side, it's all great fun.
