Yes you can reuse the oak, it will impart less colour the more times you use it but it will still have the reactions in the spirit you are looking for from the oak but will take longer. I personally go for a minimum of 12 months on anything i make.
I have charred some with a blow torch but otherwise i haven't retoasted and just used it as is. If you are looking for "value" you could use half new and half 2nd/3rd use etc.
There is an oak toasting chart which you can find here somewhere or on the internet.
