Narrative:

We failed to switch to tower controller and get a landing clearance. Lack of recent flying experience; my 2nd leg after 3 months off. Fatigue due to not getting much sleep in before red eye flight. Lack of recent flying by non flying pilot as well. Slam dunk approach by controller; task saturated. I needed the gear and flaps out and was asking for them at the same time the controller was switching us to tower.I don't recall the approach controller asking us a second time to switch to tower; the tower said later when we called them that they tried us on guard (I did have it tuned and up a little bit; surprised I didn't hear it) and did light signals but didn't mention calling approach control and asking them to tell us to go to tower again. The other thing is tough; I know why the pilot flying doesn't do the flaps and gear himself; but in this case my asking for them right after the non flying pilot read back instructions to switch to tower I think caused him forget to switch over and check in. Lastly; it's pretty ingrained in me to call out 'landing' before touching down; but going forward I'm going to be less concerned about saying the word and concerned with the 3 things we need to land.
