Incidentally, I did not answer my own question. I can tell you what I do, but I had no idea what's considered "proper" but it sounds like I'm in the ballpark.
For a buffet, it depends on what the server actually does for you. I grew up hearing 10 percent and that's still what I would consider a minimum. I don't give the full 18-20 percent that's standard for sit-down service, since there is less work done (no order-taking, no bringing of dishes, etc) and the waitperson can serve more tables at a time (so he/she receives more tips), but I increase the percentage if they are generally available and helpful.
For carry-out, my answer is closest to eatchicago's; it's situational. If it's a place with a big carryout operation and its own carryout counter (e.g. gyros and pizza places), often nothing. If it's a place where there's more of a personal relationship, such as a bartender who retrieves the food and verifies the accuracy of the order, then I typically give a couple of bucks or so.
For delivery... I almost never get delivery, but when I do, I would typically be giving a round amount so that I can hand the driver one bill, usually a five, assuming it's just a single small bag of food. More (maybe a ten) on a very rainy or snowy night.
Of course, there are always additional factors that can increase or decrease the tip. For example, what sparked the question in my mind was the Mother's Day brunch at one sixtyblue. The buffet was much more expensive than most (at $65/pp plus a $12 mimosa, 10 percent was already over $14, which is a pretty healthy amount) and, unlike most buffets, coffee service was on the buffet, not brought to the table. But OTOH I tend to give a higher percentage at a nicer (more upscale) restaurant, when the food and atmosphere are nice, when the server remains available and helpful, etc, so I ended up leaving higher than 10 percent.

As noted above, I like to be able to hand the driver one bill. I'd probably give a five as a minimum, but if there's a large order, I'd make it ten. If I'm going up from ten (if there's so much food he's making several trips back and forth, terrible weather, etc)... well, I never get that much food delivered, but if I'm going up from ten, it would be to give a twenty.
