I'm a fan of down to earth, and that's what i use for bat guano. I don't use bat guano in my soil, but i do use it for a mid flower top dress
Recommendations for dry fertilizers and dry amendments can vary greatly based on what you're trying to do, so a little more information would be helpful. Are you trying to build a no-till soil?
As for generic recommendations for dry amendments to consider, here are a few:
Down to Earth Bio-live
Insect Frass
Neem Seed Meal
Kelp Meal
Rock Dust (I use basalt, but azomite is sometimes easier to get)
Oyster Shell meal
Agricultural Gypsum
Crustacean meal
