I have OpenWrt Attitude Adjustment 12.09 installed on a TP-LINK TL-WR743N/ND. I'd like to update the firmware to a more recent release but cannot figure out which image to download. Could someone point me in the right direction please?

If you look carefully at the data tmomas linked, you'll see that it's now on the "tiny" target meaning that LuCI no longer fits with an up-to-date kernel and current "basic" utilities.
Edit: My mistake, the "tiny" target, at this time, continues to include LuCI.
Given that Attitude Adjustment is over five years old now, an upgrade is definitely a wise approach given the number of security vulnerabilities in Linux, third-party utilities, and 802.11 itself found since then. Even on the tiny target, your device should still run as a wireless router though you'll have to configure and manage it through ssh.
luci is preinstalled in the (release images of the) tiny target(s), at least so far - with kernel >=4.14 it will become increasingly difficult to fit luci into 4 MB, so this might have to change in the future. Having luci preinstalled might however mean that release images can't be built for all devices covered by these targets (there's still the option of using imagebuilder for these devices), in some cases looking at snapshots (which don't have luci preinstalled) might provide a working image though.
