I managed to hold Bagdad, Yerevan, Tibilisi and Tabriz with only two mangonel units and half a stack of saracen/spear militia. I deployed all troops in the city square to hold the enemy line while the mangonels lop projectiles into the crowded Mongol ranks. It will be carnage and you will lose many men (but militia can be re-trained the next turn so no big deal). All you need to do is hold the line. When the Mongols break through, you've lost the city. One or two fast moving cavalry units (turkish HA are cheap and great for this task) to chase routers will be helpful too.
Don't bother when they take some of your settlements, some will fall eventually, but the Mongol hordes don't last forever. Anatolia is the most important part of your empire, it must be kept secure at all cost. Everything else can be taken back and you can always use a small (and mobile) force to go behind the Mongol lines which can net new castles and cities for you to defend and some Mongol stacks will turn around and relieve the main front.
In my late-era Seljuk campaign I'd conquered most of Khwarez territory around 1320. The Mongols usually leave only one unit behind to defend and some cities are without a garrison - they are easy targets around 1270-80 (no more Mongol stacks spawn).
Ok I've been trying your tactic where you defend in the town square and it's hilariously effective.

I wonder if this same tactic would work with ballistas. Since they have a bit of arc to them they might be able to fire over the V formation and into the crowded mongols sitting back shooting arrows.
