How about "The Man Trap"? With the possible exception of Trelane's stuffed-and-mounted salt vampire (that was probably just a budgetary thing), the only thing I can think of that references it, whether on screen or in print, is my own student short story, Inteview with Dr. Ambrose Crater, or "The Salt Vampire Ate My Parents."
Nancy Crater nee Bierce appears in flashbacks in A Choice of Catastrophes
I'd be really surprised if there's a single unreferenced TOS episode. It's got to be a late-series VOY episode, if anything. "Live Fast and Prosper"?
