Carrying remote VLAN via 2 routers to the local gateway

I have a serverA (192.168.15.1) from site A and VLAN is 15, however the VLAN 15 gateway is set at site B (192.168.15.254).
There are two ISP routers as a metro role to connect each other by subnet 10.0.0.0/30.
My question is how can I get past those two routers? Could any one give an example to accomplish this? Thanks.
PS. I can ping from serverA (192.168.15.1) to an interface f0/0@R1(10.0.0.1), no more further.

You need to provide a lot more information. For example, what are the network device models and configurations? You can refer to the Network Engineering Question Checklist for guidance, then edit your question to include the necessary information. Speculation and guessing are off-topic here, as are questions about network not under your direct control

Do both 192.168.15.1 and 192.168.15.254 use the same /24 subnet? Can you configure the routes on R1 and R2? Is it possible to split 192.168.15.0/24 into 192.168.15.0/25 and 192.168.15.128/25 ?

You can use Ether in IP, defined in RFC 3398 to tunnel ethernet through IP, if you equipment supports it. It's similar to the VxLAN approach, but a little simpler and older.
If you don't have those and it's desperate, you could think about proxy ARP. It is really not recommended.
Do you have a particular reason to bridge like this?
I'd suggest you strongly consider renumbering so you can just use ordinary IP routes. Perhaps you are nearly there already, if 192.168.15.0/25 is left and 192.168.15.128/25 is right? Renumbering R1 f0/1 (.126?), change masks, add routes to R1 and R2.

You can use VxLAN, defined in RFC7348, to span a VLAN onto different sites.
Basically it encapsulates a VLAN into IP.
This off course add some overhead, and your routers at each endpoint need to support VxLAN
