This may change over time, but the only pieces I played at the recent recital were pieces with students. My "showcase" teacher piece--if you want to call it that--was with a beginning student who had learned a portion of "I've Got Rhythm." I rewrote it in F Major for her and added a few things. She started us off on a keyboard by playing the A portion solo, "I got rhythm, I got music, I got my dog (LOL) who could ask for anything more?" Then I came in with a jazzy version and played while she repeated the melody. I was going to have her play the B portion "Old man trouble...", but it just wasn't coming together. So I played that portion solo, then we came back in together for the end. In this way, I played for my students, but it was still all about them.
