Enough Weyermann Munich Amber extract to get your gravity up in the range of 1.048 - 1.056
Steep a bit of Carafa Special II (~1/2 pound) for color.
Use German hops, and aim for around 20 IBU bittering (60 minutes), add a bit (~3 IBU) of the same hops with 20 minutes left in the boil.
Pick a lager yeast (I've used WLP830 with nice results), make a big starter, and ferment at ~50F. When finished, rack to secondary and lager at 35F-40F for at least 4 weeks.
