The Chalmers Center has wrapped their book Helping Without Hurting in Short-Term Missions with a set of free tools: online videos for before, during, and after trips, a social media guide for teams, and practical guidelines shaped by research and real stories (https://chalmers.org/books/helping-without-hurting-in-short-term-missions/). It’s ideal for churches that want their short-term teams to serve the materially poor in ways that foster long-term change, not dependency.

I remember using this book 25 years ago.
