Directing traffic from different LAN/VLAN to a specific WAN

Hello everyone,
I’m new to Mikrotik RouterOS and I need some assistance. I’m setting up a network where I will have 2 WAN connections, one WAN for general internet traffic and another for VoIP Phones, I’m doing this because of speed limitation from ISP, had to get 2 DSL services.

I’m using RB2011UiAS-RM and two managed Cisco switches , one of the is POE, for the phones.

Basically what I want to do is put all the computers on LAN (192.168.105.1) and route the traffic through WAN1 and all the phones on VLAN (192.168.110.1), and route vlan traffic through WAN2
How do I go about setting up the routes on the mikrotik?

Thanks for your help
