It sounds to me less like you have writer's block and more like you don't know where your story is going.
A good story has a point it is trying to make, and goals its characters are trying to attain.
Conflicts (and action scenes) are usually things that hinder your characters in reaching their goals.
The action scenes are the sugar coating on whatever point it is you are trying to make. You (as the author) have something to say. Your character's goals are points in your arguments. The action scenes are to keep your readers from getting bored.
If all you have is a series of action scenes and no idea why they should happen, then you aren't telling a story. You are compiling a pointless series of anecdotes.
- Figure out what you are trying to say in your story.
- Set goals for your characters that relate to the message you are trying to convey.
- Use conflict and action to keep the reader interested.
- The conflicts should relate to your message and/or the goals of the characters. Action for action's sake is fluff nad makes your story worse, not better.
The "point" of a story can be just about anything.
Surely you, as a person, have some point of view on some subject that you would like to express.
Find some theme that interests you, or that you think other people need to be thinking about. Use that theme as a background for your story. Your protagonists are the characters working to a positive resolution for the theme. Your antagonists are those actively opposing your protagonists' efforts.
To get back to your (rather vaguely described story,) you need to ask yourself why your characters are in that forest. Why are they there? Why did you put them there, and what are you trying to tell me by the actions of your characters in that forest?
If you know the answers to those questions, then I'd think you'd know what to do after the action scenes. Action scenes are conflicts. They resolve some point, and your characters resume trying to reach their goals, usually with a change in plans or attitude that results from the conflict.
Since you don't know what your characters should do after a fight, I'd say that you don't know what story you are trying to tell. You (as the author) must know where your story is going even if your characters don't.
One of my favorite stories comes from the original Star Trek series. It is full of action and tension - and has much to say.
The Devil in the Dark is composed mostly of action - chasing a monster (devil) through the dark caverns of a mine.
In the end, the "devil" turns out to be the humans who have been destroying the eggs of the Horta - which has been trying to protect itself and its eggs from the encroaching humans. The "Devil in the Dark" are the humans.
The "Devil in the Dark" is also the fear exhibited on both sides. The Horta fears the humans, and the humans fear the Horta. The fear on both sides leads to killing and deaths.
Once both sides face their fears, the story resolves peacefully with the miners and the Horta (and children) working together.
It has a couple of points to make, and does so. It is also entertaining and almost entirely action.
It has a theme, the characters have goals, and it has conflicts. The author of the script managed to get all of the elements together and make his point.
By the way:
Those views above on the content of stories are those of a reader (me.) I'm not an author. I'm just a guy that has read northward of a thousand novels and even more short stories.
What I wrote above is what I expect from a story.
If the characters don't know where the story is going, that's fine. They are like regular people who can't see the future - they deal with things as they come.
If the author doesn't know where the story is going, I'll drop the book in a red hot second and go look for a better story.
