Is there any simple/proven tube buffer plans out there for DIY? I like the Yaqin design that Pacific Valve & Electric has.

This might fill the bill for you.

You can eliminate or include the switching and volume controls.

My first choice would be the White Cathode Follower. The Broskie CF doesn't look half-bad either.
I bought one of the Yaquin single tube units. It was running a 6922 at a very low 1 or 2 mils of current as a standard cathode follower and it made the signal sound way bloated, underdamped, and narrowed bandwidth. I replaced the cathode resistors to allow the tube to run at 4 mils and it was much improved. My purpose in buying it was to buffer the output of a passive preamp that had an 8k output impedance trying to drive a 20k input impedance to the power amp. after the changes it sounded pretty good. I would run it higher but I'm unsure of what the power transformer can deliver.
