I'm not sure if you a clinician or educator, but I can give you suggestions for what to expect if you are teaching a clinically-based course. I taught (2) 3-credit classes in the graduate program and guest lectured for undergrad. The level of detail you will be asked will probably depend on how many credits you'll be teaching.
The interviewer may ask specific knowledge questions about the requested teaching topic, so besides your CV, you should be able to pull out specific case examples that demonstrates a problem you encountered and how you (and a team) solved it. You should be able to speak to possible topics of your course that match your experience but also reflect current evidence. You should be able to have at least 2 possible invited speakers in mind who are known in the topic/field you're teaching. Make sure you are clear on your world view or underlying epistemology. Your point of view on therapy or instruction may not match theirs; try and find out what their perspectives are on the topic you'll be teaching.
The interviewer may ask: (a) about the range of experience with diagnostic cases across the lifespan, (b) if you have a grasp on any controversies in the field on different approaches to care or theoretical differences that may impact what/how you teach; (c) if you have access to current research articles; if the person who is interviewing you is knowledgeable in the field you'll be teaching, you should have a list ready of the top 10 articles/researchers who are leading the field in the topic of instruction and see if that person agrees/disagrees with your choices.
From any field, you'll want to have some facts/info that tells them you know how to teach adult learners. I don't know your timeline, but it would be a good idea to get a copy of McKeachie's Teaching Tips, 14th ed. by Svinicki & McKeachie (2104). For example, I used a problem-based, experiential learning designs. You may want something a little different, I'm not sure of your topic, but this book is appropriate for any college teaching. Being able to speak the lingo of your teaching philosophy will be helpful.
If you are offered the position, make sure you ask for a syllabus template. I didn't ask my first year, and my way of organizing did not match what the students were used to seeing, and even though approved by the chair, I ended up making too many changes during the year.
Ask if they have people to help you learn the course management system. I learned Blackboard a month before I started. Ask about the equipment you'll be using to teach with. The classroom I was given had a bulb that overheated and there was a specific way to turn on/shut down all the equipment.
Ask if the chair or other staff person will be observing you at any point. If so, ask what they will be looking for, then make sure you get a summary in writing.
Ask how the students are expected to address you. I came from a formal university and I was a little shocked with the informality between teachers/students. A lot has changed, but you might want to ask about that upfront.
Good luck! I really enjoyed being an adjunct. In fact, it inspired me to go back and get my doctorate. I wish someone had given me a heads up before I started though, so hopefully this helps.
