The general Soviet strategy will be to extricate as many forces as possible from the initial encirclement, build defensive positions to the rear, and run for those defensive positions as fast as possible. There will also be some temporary blocking positions set up to slow the Germans and attempts to blow various bridges by the Soviet forces.
I think it's also critical to contest the air by late 1941 so I'll build a combination of Flak and Fighters to prevent the Luftwaffe from having free reign to pulverize my main defenses.
On turn 1 I also build some trucks and a lot of engineers. The trucks will be used to ship demoralized troops away from the rampaging German spearheads, and the engineers will be used to blow bridges and start building fortifications.
Here are my turn 1 losses seen when I open the first turn:
