Career Professional now working as a Professor and being pressured to publish - Where does one start?
This is either an abuse of an adjunct (I doubt they are paying you enough for this!) or they're grooming you to bring you properly on board.

If it's the latter, or if your interest is coincidentally piqued, I suggest you start with two things:


Find a mentor.  This person doesn't have to be in your department, and doesn't have to be an expert in the same area as you.  If you don't find one quickly by yourself, have whoever is pressuring you suggest someone.
Go to Google Scholar and type in some key words from your area.  Just start reading.  Don't read anything you don't find interesting.  After some reading, find out a bit more about the features of Google Scholar (for example, once you find an article you're really excited about, click where it says "Cited by").

It all starts with "I wonder...."

Have fun!
