Trunk over wifi ?

I have got two routers. The main one is Mikrotik (7.14) and secondary OpenWrt connected to Mikrotik over wifi in client mode. In OpenWrt there is another wifi mode: master with SSID for client devices. Also there are two vlans on both. Is it possible to trunk these vlans between routers over wifi without any gre or eoip tunnels ? Or is it the only one possible solution ? I want to achieve something like this: if client connect to OpenWrt wifi it will get IP from mikrotik’s dhcp server from proper vlan.
