I missed this thread the first time around, and am glad it was revived. defcon's link is helpful.
Here's something that I've been trying the last few days. It helped a little.
Step 1. Find a fight scene in a book. It should be one you like.
Step 2. Retype the fight scene, but double space between each sentence. (That means hit Enter twice, not hit Spacebar twice.)
Step 3. Consider deleting the sentences that aren't describing action.
Step 4. Under each sentence, retype it with the words replaced by descriptors of what kind of word they are.
Example: "Bob hit Joe with an axe, hurting him" would become "(Attacker) (Verb: Attack) (Target) (Description Phrase) (Result)." If your actual chosen book has a sentence as boring as "Bob hit Joe with an axe," find a better book though.
Now, do that for every sentence and you'll start noticing patterns and a sort of flow to the writing.
Step 5. Switch to another book and repeat this.
Do this enough, and you start getting a subconscious idea of how most writers format action sentences. This doesn't mean its necessarily the best way to write, just the most common way, but that's a good start, right?
Formatting an entire action paragraph, action page, or action scene is much more complicated, but you could also break them down if necessary. (Sentence: Antagonist Attacks.) (Sentence: Main Character Defends.) (New Paragraph) (Sentence: Main Character Thinks and Attacks).
But more importantly, retyping from a lot of different books and then reading the sentences for structure can kinda imprint paragraph/scene patterns in your mind and give you a slightly better idea of pacing.

Also, I tried the "heavy description of sights, sounds, smells, etc." and everyone told me that it was too wordy and boring and nobody cared about that stuff. Rereading my favorite action novels, the description is always very bare-bones and leaves a lot to the imagination. So I'd recommend not describing much.
On the other hand, it's really great if each thing you do describe is really symbolic or emotional in some way. A few short but important sentences can go a long way.
