Hoping I understand you correctly, won't something like this work ?

Put the interfaces you want to run dhcpd on in /etc/dhcpd.interfaces.

/etc/dhcpd.conf:

shared-network LOCAL-NET {
        option  domain-name "my.domain";
        option  domain-name-servers 192.168.10.1;

        subnet 192.168.10.0 netmask 255.255.255.0 {
                option routers 192.168.10.1;

                range 192.168.10.32 192.168.10.127;
        }
}

shared-network WLAN {
        option  domain-name "wlan.my.domain";
        option  domain-name-servers 192.168.20.1;

        subnet 192.168.20.0 netmask 255.255.255.0 {
                option routers 192.168.20.1;

                range 192.168.20.32 192.168.20.127;
        }
}

// end of /etc/dhcpd.conf

LOCAL-NET serves the wired interface configured as 192.168.10.1
WLAN serves the wireless interface configured as 192.168.20.1

Your /var/log/daemon may show dhcpd messages telling you for which interface
you're missing subnet definitions.

I think the trick is to have subnet definitions that correspond to the ip
addresses of the interfaces you want to run dhcpd on.
