Here's a quote from a good article about American Toad husbandry and the link to the full article which should give you some useful guidance: "Toads should not be fussy eaters. Healthy toads are usually actually quite pudgy! If you are housing them correctly within the suggested temperature range, then they will accept crickets, mealworms, waxworms, earthworms or superworms of appropriate size. They usually consume anything that they can fit in their mouth. Gut-loaded crickets can make up the majority of the diet; however, variety is the spice of life, and the more you can vary a toad’s diet, the better off it will be. During warm months, catching local insects (nontoxic, of course) can provide added variety. Moths seem to be particularly relished by most toads. In the wild, they eat grubs, spiders, worms, insects, slugs, snails and other invertebrates. If your toads are wild-caught, try offering them what they eat in the wild."
