I have a double on my Salsa Vaya that has a 50 on the big ring that I do not use much at all. I would like to change out to something smaller and more useable. Also, rather than going huge in the back I wouldcrather drop the small a few teeth as well.

I will try my LBS, but they aren't open now. Do any of you know what might be available for the Compact Double? Anyone switch out theirs?

Are you sure you have a Shimano compact? The Vaya has Sram Cranksets as OE.

Shimano does not supply a range of ring sizes, they only offer repacement chainrings.

Here is a great source for chainrings, Peter White also provides very good info: https://www.peterwhitecycles.com/chainrings.asp

You might consider a Cyclocross crankset, these have 46 & 36 chainrings.

For a 110 BCD (Compact) crank, you are limited in the smallest ring- 34- that you can have. But for the outer ring you can get many different sizes from 38 to 50 and beyond. There is a compact triplizer available from Origin8? that will replace the inner ring and add a standard 74 BCD granny ring, which can go down to 24 teeth. But then you'll have a triple crank, and need a new derailleur, shifter, bottom bracket, etc.

There are several sources of after market chainrings
You have 130, or 110 bcd..
minimal tooth counts.. 130 .. 38t ; 110 .. 34t,
though the French TA company machines the physical minimum 33 tooth ..

Good sources and I will dig into them. I just looked at my inner rings and have a 34 on the small ring. I bought the Vaya frame and built it out with Shimano components. I was used to the shifting of Shimano and didn't want to retrain myself for the SRAM. Went with Mavic rims though, with XT hubs.
