Intermittent Brake Smoking on Tahoe

2000 Tahoe (new style), 5.3L, 4x4, 85,000 miles, dual piston calipers in the rear.
I'm a novice mechanic. On Sunday, I replaced the rear brake pads on my 2000 Tahoe. My wife drove it on Monday and complained about brake smell. On Tuesday, she didn't notice any smell. Her trips are about 10 miles.
Today, Wednesday, I drove it about 20 miles and when I stopped the left rear brake was smoking. The tire was warm as compared to the other three. I didn't feel the wheel.
I let it cool down for about an hour, drove home and no smoking brakes.
Any ideas?
Thanks!

They have a known problem with those aluminum calipers freezing up. You need to replace both calipers and the pads again now too because they have been overheated and glazed over.

Agree - It would be old enough if they are original anyway. Also - you tell me if this has the small drum brake inside hidden by the rotor for the parking brake? That can mess up too. It doesn't self clean nor drag from use while moving normally and have caused problems I've dealt with,

If cable for parking brake isn't going to the caliper it's going the those little drum brakes -- you need to remove the rotor on those as it's also a drum brake you don't see. They can get junked up, rusted, dirt or who knows to mess those up? Cables must be free also like any.
If the service brake you should clearly see discoloration on the side that smoked vs the other and do both side of anything equally is always suggested.
Clearly you didn't service the rotors or you'd have known about the little drum brake and that's not a good way to do brakes,

What exactly do you mean by "service the rotors"? Are you strictly talking about having them turned (or replaced if needed)?

If you replaced worn pads they needed it. Just tossing in pads is HACK, can create noises with the new pads, most have a rusty or less worn outer area and so on. Pads will break in to a new or resurfaced rotor tons better.
I can't force anyone to do it their way and there's a place with a sign near me stating they'll just toss in pads, chain place no less. With this even if you chose to fake it you would still take off the rotor and check things out at a bare minimum, clean up the hub to rotor contact area and inspect that parking drum brake.
I can't say that is causing the problem at all and your trouble was extreme enough I do think caliper is the issue so far. Have to suggest go back and do it right,
