If you want to do a full 5 gal batch in that pot you can also dunk sparge in a bucket rather than mashing the full volume. After the mash drain, dunk the bag in the bucket and stir the crap out of it, then drain again and add to the pot. A very basic American wheat recipe that is a good lawnmower beer is 50/50 2 row and wheat malt, to about 1.050-1.055, bittered and finished with something like perle, hallertau, liberty to about 23 IBU's. I like WY1010 but you can also use any neutral ale yeast or the 320 mentioned above. As Lefou pointed out you won't get banana/clove with these, which I assume is what you want as you said American style.
