Sounds like you need a resume that' s very focused on your academic achievements and downplays work history. You can do a layout like this:

Qualifications Summary
Outline your credentials to teach, and also include your teaching philosophy. Remember that schools want to hire the bestteachers, and especially teachers with ideas that match those of the school ordistrict. So, do some research and find out what is most important to theschools that you are interested in. Also emphasize any subject-matter expertise that would be valuable in the classroom.

Key Skills
Even though you haven' t taught before, you probably have related/transferable skills (like delivering presentations, training others, developing training programs, etc.). Include a bulleted list of skills that schools would find valuable.

Education
Highlight academic achievements, extracurricular activities, honors, awards, etc.

Experience
You probably have transferable skills from your positions held, so highlight any skills and accomplishments that schools would find relevant.

You might have other headings, like Volunteer Work, Tech Skills, Foreign Languages, etc.
