This is possible if you make the wireless router a node on the 10.10.10.0 network and NAT the traffic from the 10.70.10.0  network to the 10.10.10.0 network (schema attached).  Alternatively, you can put the wireless router into Wireless access point mode and it will act like a switch, no further config required (schema2 attached).

Allow me to correct myself.  I misread you initial question.  You have two networks on the same router, correct?

In this case, you should be able to accomplish this.  All you have to do is do configure the same vlan on the BVI and FastEthernet interfaces

Short config (some output omitted):

!---Wired---

interface FastEthernet0

switchport access vlan 10

interface FastEthernet2

switchport access vlan 10

interface FastEthernet3

switchport access vlan 10

interface FastEthernet4

switchport access vlan 10

!---Wireless---

interface Dot11Radio0

ssid SSID-name

vlan 10
