Build 14-4s with engineers and recon. If you can, defend the mountains with 14-4 mountaineers. They cost more infantry equipment but have more org and better performance, especially in the mountains. Make good use of the Czech forts. As someone mentioned earlier, you'll have to cycle divisions. But the engineers are important for blunting the initial push.
Don't build up your own forts too high (I'd suggest level 3 or 4), since the CIC can be used to build up your mils.
As far as doctrine goes, I'd suggest grand battleplan for entrenchment or mass mobilization for manpower (but you won't get that manpower until 39 or so).
