Specialty grains plus malt extract:
Dave Miller describes his Classic All-malt Pilsner as being a "generic" pilsner (1995, p. 321). For a Czech style, soft water, lower fermentation temperatures, and a higher hop rate are needed. Moderate water hardness with less hopping is a more German pilsner style. Continental pilsner malt and lager yeasts are recommended.
Another generic option is to use American two-row malt, American versions of German hops, and ale yeast for an American cream ale.
