You're adding a host route, whereas you need a network route. Try:
$ sudo ip route add 192.168.1.0/24 via 192.168.1.1

Or, with the older tools (a bit rusty):
$ sudo route add 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.1 dev
tap0


I think this setup might need additional configuration on the outside,
because you need to add the same subnet route on your Internet
modem/router. I don't think qemu gives you NAT for free...
