Yes you can.
There are the council or Belediye buses which go from inside the otogar. If I remember correctly you will need to catch the number 93 or 94. The destination board on the front of the bus will tell you where it is going. Look for Lara.If in doubt just ask the driver he will only be too pleased to help you.
You cannot catch a Dolmuş from inside of the otogar.
