in actual response, grabbing a bog standard lager kit and replacing the sugar with Rice Syrup should get you close. Bud's flavour (or lack of, as that's how it's marketed) comes from the rice which boosts ABV with almost no taste, and from fermenting on beech cubes which keeps it off the trub. that's pretty pointless to emulate at home, but I would honestly suggest something like a pilsner kit (as they taste very clean) and adding rice syrup/DME 50/50 instead of beer kit enhancer. give it a few months, send it through the lagering process with lager yeast if you have the option to, and then check that out. you'll need to bottle too for lots o' fizz.
