In your case it's simpler just use two /32 static routes

We need to make two new terms which are the gateways for WANs
WAN y.y.y.y gateway is y.y.y.gw
WAN z.z.z.z gateway is z.z.z.gw

So simply specify a /32 route for the EOIP tunnel traffic
Code:
/ip routeadd dst-address a.a.a.a/32 gateway=y.y.y.gwadd dst-address b.b.b.bv/32 gateway=z.z.z.gw
The basics here are that only the tunnel traffic itself actually goes to the remote public IP. All the site to site traffic is going thru the tunnel which does not involve the public IP. Your tunnel traffic itself now has no option but to leave via WAN you specified.

It's a trick you often use when you want to form a tunnel and have the default route go thru the tunnel when you would do something like this
Code:
/ip routeadd dst-address 0.0.0.0/0 gateway=tunnel.gw add dst-address a.a.a.a/32 gateway=y.y.y.gw
Everything in the above goes thru the tunnel except the tunnel communication traffic itself.
