Unfortuantely your post doesn't really contain enough information to give a precise answer.
As you don't specify the netmasks being used I'll have to second guess. I assume you're using 192.168.2.0/24 (255.255.255.0) on the Ethernet and 10.0.x.0/24 (255.255.255.0) on the Wireless.
If you're using less than 24 bits on the Wireless then these will be bridged, not routed and you'd have to add a bridge to the MikroTik node and the ports to the bridge.
To start with your choice of addresses for the wireless interfaces would be better if they were:-
This makes routing a little neater and is a bit more logical.
Using a 24 bit netmask gives you up to 253 IP addresses free on each wireless, i.e. 10.0.x.0 is the network address, 10.0.x.255 is reserved as the broadcast address and 10.0.x.1 is the interface address, hence 256 - 3 = 253.
If you need more IP addresses then the netmask needs to be lower than 24 bits and this will change everything below. So decide how many addresses you need, if it is more than 253 per wireless card then reply to this post with the number you need and I'll update the information. I would have though 253 is more than enough, especially if you set the DHCP lease time to a low value, e.g. a couple of hours.
You need to add a 192.168.2.x address to the MikroTik node's ethernet interface.
Add a route for 0.0.0.0/0 gateway 192.168.2.253 to the MikroTik node.
You can either add one route on the gateway or 4 individual ones, which method you use will depend on whether you intend to use 10.x.x.x addresses elsewhere on your network.
The neatest way is to add one route for 10.0.0.0/22 (255.255.252.0) gateway 192.168.2.x, where x is the address you've allocated to the MikroTik ethernet interface.
Alternatively add 4 routes 10.0.n.0/24 (255.255.255.0) gateway 192.168.2.x. (n is the incremental number given to each wireless interface).
If your gateway supports RIP then you could try that, however that's a whole new ball game and many domestic grade routers either don't support RIP at all or support it poorly.
