Hi kcfisch3,
Thank you for posting to this forum!
You're on the right track by highlighting teaching/training experiences, but you should also emphasize your subject matter expertise. The school would most likely be interested in your industry success and hands-on knowledge of the subject(s) you wish to teach. So include accomplishments, accolades, awards, contributions in the field you would like to teach. You can also highlight your own academic achievement such as honors, scholarships, and a high GPA.
Your cover letter will be equally important -- you need to explain why you are seeking an adjunct teaching position and what you offer the institution.
