How do I create a vlan while using relayd? For tor

I was looking into how to do this, and it just seems very difficult to understand, especially since I am not familiar with openwrt at all. I am going to look into this again later. Below are the only links I found that may be relevant. (I should emphasize that I don't want everyone connecting to this router or at least this SSID to use tor, it is actually just for me, like 1 or 2 devices)
