If you are over 21 you may petition for your Dad and he would be considered an immediate relative. After he left in 2009 he triggered a ten year penalty and assuming he has not tried to come back since that date he is eligible to apply for a waiver of that penalty if the equities are there. You should have a consultation with an immigration lawyer and include him on the phone call to make sure all the facts are known about his immigration and criminal history before starting on this complex process.

I agree. Understand he will need a waiver for the unlawful presence bar which was triggered in 2009 when he departed. You will also need to speak to an attorney about any other (possible) bars he may have which may also need waivers. He will need to consular process and file for the waiver after filing the I-130. Be sure to consult an excellent AILA attorney.
