Extracurriculars to make my application stand out?

I’d like to transfer to the University of Memphis next year, but I’m an OOS student and I’d never be able to afford the tuition.
Their honors program offers “Non-Resident Honors Student Awards” which is basically just a waiver that allows the student to pay in-state tuition. They only offer 30 a year on a competitive basis, with incoming freshman receiving primary consideration.
I’d really just like any advice on what I can do to make my application standout, whether it be academic or community service-wise or anything.
I’ll have a (relatively) high gpa, somewhere around a 3.8, a founding officer of a community service club/anthropology club (having held several different positions), honors student, and member of another community service club.
What more should I do?
