Say her name, and when she looks praise her and give her a treat. Her name should always be with something possitive.
For teaching come get a long line. They sell tham at pet stores. Mine is 30 feet and it's perfect. Take her outside and attach the line to her collar. HAve lots of treats in your pocket. tell her "come". If you can lure her in with a treat do that, other wise grab the line about a foot away from her collar and give a little tug, say come, and pull her to you were.
This is just so she learns what come means. If she knows what come means, and is over 6 months, then you can start proofing her.( making sure she'll come everytime in distractions) I recomend a prong( also called pinch) collar. They look evil, but are very humane. The prongs don't poke into the skin, but when you pull on the tab( an about 1 foot leash that is always attached to the collar) the prongs come together and pinch the neck like a mother or Alpha dog( you) would give it a correctional nip.
If she knows come then take her out with her long line on and let her run around. Tell her "come" in a clear voice. If she comes reward her and give her a treat or just praise and pet her a lot. If she doesn't come the first time you say. Say "no no no" all the way up to her, give a quick pull and release on her collar like you would with the tab(1 foot leash) on, repeat "come"( after the correction) and pull her to where you were( hands still about a foot away from her collar.
Your dog will learn that you are the leader of the pack and he will want to please you and listen without being bribed. If you rely on bribind then as soon as something more tempting( a bunny) comes a long he'll think. Nah , don't want a treat right now, I want a bunny! and off he goes.
