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:

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