It is hard as recognised strategies can be very individual and applied very individually.
I'm not so much for rewards and special jobs for behavioural strategies of a problematic nature rather I'd see if they were recieved well for self confidence and issues of independance.
Promoting positive behaviour can be about being prepared - being able to spot a situation and step in - not necessasrily closely. To have colleagues around that are aware of any ongoing situations & triggers that can help / be called on to help diffuse and distract .. have parents as partners working together to promote / get through what ever is going on. As already suggested smiling, praise and valuing what's being said.
If you think of some of the 'viewed socially unacceptable behaviours think about how you would handle the situations..
Spitting, biting, hitting and punching, throwing, kicking, screaming, hair pulling, pinching - refusal to stay / leave, snatching - sharing & turn taking - not sitting, standing, following - queueing, leading, complying, answering, stamping feet - sulking, fear, anxiety impatience and anger ..

Other positives strategies : doing things that are enjoyed - unusual, interesting, different - look at the reasons why anyone isn't enjoying them and look to improve / change things to suit all ..
Where compliance is the responsibility of adults eg: following curriculum guidelines, planning requirements and other mandatory / necessary recommendations and behaviour may become a percieved problem - look to explain why certain things are being done and at how they are being done ..
That may include fire drill requirements, group meetings, circletimes, expectations and routines for line up activities - putting on shoes where no shoes want to be put on
