I'm trying to create a quick and dirty monitoring system. I'd like to run each track through my headphones and run my vocals through my headphones at the same time. And send my isolated vocals back to the computer for recording. Using the computer itself creates way too much latency. I think a monitor system in the middle would fix it, but I'm having trouble with the wiring.
I've drawn a schematic of what I'm trying to do

Sorry, but I moved your post here from the Guitar Wiring area, as it seemed more appropriate here.
I don't have any good answers for your question. Do you envision this monitor as being entirely a passive device? Your rough drawing indicates that the mic signal will need to be split to the amp, which will need to be a line-level output, as well as to the headphones, which will be a speaker-level output. I'm not sure whether all that can be done passively, you may well need a preamp of some sort in this box.
Also, I think you will need to isolate the two signals, probably with a stereo jack and cabling, or the volume pot on the backing track line will also affect the volume of the mic feed.
But that's just off the top of my head, others will probably have better suggestions.
i reckon this would be a job for a small mixer desk. I have an old very small Behringer Xenix, its 15 years old an i use it every day. With that, I have one mic input that can be set up to the right level with a bit of EQ, then sent out to a line-in on the computer, or modern ones have a usb output. But I can also bring in a cd/tape input (its that old) and send that to the phones too.
A better mixer would start to have separate output channels for foldback etc, and with those you could set up a mixed monitor feed and also a pure mic signal.
