When I was finishing up my Ph.D., I helped teach one class that was in my area. I think I taught two chapters. That was all the formal pedagogical training I received. I helped another professor in the department by leading a couple lectures with one of her courses, too, but that wasn't anything the university did. When I started teaching at UH as a lecturer, they gave me the book and materials that the previous professor and other sections of the class were using. After a couple of years, I picked a different book, but I still use some of the materials.
I would reach out to the department chair or whomever is recruiting you and ask if they have any requirements for the course and can they give you any materials and books. You can also look online for relevant materials. I know that a new fad in K-12 is having ChatGPT to provide you with ideas and materials. You give it details about what information you need to deliver to students, and you can ask it to provide lesson plans or lecture notes, tests, projects, and more. I don't know if that has made it to colleges and universities yet. It isn't anything I've used.
I'll add that in 15 years at UH, I've never had anyone from the department or university sit in my class. They do look at student surveys, and I suppose if those were bad they might dig a little more, but there's a lot of leeway to run your class how you want.
Edit: I went back and looked at my transcripts, and I have a bunch of seminar classes. It's possible one of those was on pedagogy, but I sure don't remember it.
