OEMs put simple, flat pieces of plastic in front of the tyres.
They put them pretty close to the tyres, and a bit more to the middle of the car.
They sometimes curve the inside part around the edge of the wheel well (i.e. facing more towards the middle of the car)
As for strakes after the tyres, a wedge shaped structure with shallow angles will do.
Put it as close to the tyres as possible, and make it no wider than the tyre itself.
It would probably be even better if you used the shape of the streamlining template, but that's rather complex in 3 dimensions.
