Correction method?

A horse is simply a reflection of those handling it, and you'll never handle the same horse twice, every time you do anything with a horse it learns from that encounter, sometimes it can be positive or negative. Correction is always best starting at the lowest possible point with every horse. 

With most horses that are 'keen' to get somewhere getting them to move their feet helps. Turning them in a circle, backing them up, walking in the opposite direction - basically anything that will teach them the more the pull the less likely they are to get where they want to go. "yanking" a horse's face teaches them nothing because they don't really understand what it means and it really means nothing because it doesn't slow them down enough. The only thing I don't use is 'pressure and release' with equipment. If you don't give release at the right time the horse learns nothing and instead can pull. I would do anything like that with a head shy horse. Even slight pressure on a rein and the horse is likely to brace against it and then it becomes a drag to the field every day. Pressure and release is meant to be used with body language, not with a halter that allows the horse to push against it. Correct pressure and release shouldn't involve physical pressure at all. 

My horse did the very same thing. Moving her feet just seemed to make her more anxious. So when she began pulling me I'd just stop and make her wait. We'd walk on when she calmed down, lowered her head and stood quietly. I just kept doing this. Her brain started to put it all together and slowly she started to realize the slow way was the fast way. 

One common method doesn't always works with every horse. Some horses need "a knot in their tail" so to speak, others respond better to vocal commands. Some you need to be more gentle and patient with. 

You want to make your desires clear to her as gently as possible.

The first thing to try is the pressure/release method.  You'll probably want to teach this to her elsewhere, where she's not so anxious/enthusiastic.

Walk with her correctly on the lead.  When she starts to get ahead, pull back on the lead.  AS SOON AS she slows, release the pressure on the lead.  This tells her she gave you the correct response.  If you keep pulling until it's a complete stop or a complete battle, she's not sure.  Do this over and over, and she'll learn what you want and get softer and softer.

That's the best thing to do - train her calmly then reinforce it at the stall by doing it over and over there as well.

BTW... if you know all the correct handling techniques...  why are you here?

Since she is an auction pen rescue you most likely don’t have a lot of her back story if any. Which is common with last chance auction horses. From the scaring on her face and being head shy it hints her face may have been beat by someone which is why she is head shy when you get firm with her but it sounds like you already guess that’s why she is like that. When she does and gets eager and starts pulling start walking her in circles once or twice. Then move forward a bit the next time she does it do it again. Continue this process until you reach your destination. Also if she gets eager when she is about to go to the pasture or into her stall. Make her wait so when you go to turn her out into the pasture. Before you let her go make her stand for a few seconds before leading her in. Then make her halt and stand still before you let her loose. When taking her to her stall. Stop her in front of her stall door and have her stand still for a few seconds. Then lead her in walk her to the back of her stall before halting her and then letting her go. All of these steps doing them everyday she will eventually learn that she will get where she wants to go quicker if she is calm and isn’t pushy. These are gentle methods that will work to correct this behavior with her it will take a while till this behavior is corrected. Just follow through with it each day everytime you are leading her and she is like this.
