Say you have 2 mikrotik routers, that are configured with ethernet lan interfaces, and both are connected via wlan interfaces. Can you build an EoIP session between these two routers and use the existing wlan IP's to terminate the EoIP tunnels?

I ask because in the documentation they typically build a PPTP tunnel first, and then use those IP's to terminate the EoIP tunnel. I am planning on bridging some ethernet traffic and transporting it over the wlan interfaces, and don't want to just bridge it to the wlan interface, I want it encapsulated nicely, so I am looking to EoIP. From its definition, it looks like EoIP does in fact do GRE encapsulation, so I am just unclear about why add an additional layer and put the EoIP inside PPTP.

You can set up "just" an EoIP tunnel directly. The additional PPTP tunnel is for security (encryption), as EoIP doesn't provide any encryption, so all of your traffic would be going over the link in (more or less - GRE encapsulated) clear text.
