The advice to get a trail cam was ultimately most helpful - I wish I'd done that right away. I tried looking in the middle of the night but was trying to be everywhere at once. Once I saw him on there and knew where he frequented, I just camped out at one of those spots quietly from 11pm until he showed up around 2:30am. He was very scared but I was able to bribe him with treats to get close enough that I could grab him. He's happy to be home!
