How can I make more birdies?

I played in a tournament today and played pretty well on a tough course. I shot 78 but had no birdies, and played the 4 par 5s 4 over. There were 5 holes where I had under 100 yards on my 2nd shot and couldn't make birdies. I'm usually decent from that range but I only got 1 close. My putting wasnt good but wasn't bad. I played the par 5s awful. The first par 5 is a 90 degree dogleg that I hit my 3 wood too well and ended up in a tough spot and made double. The next I tried to play it safe and hit into a fairway bunker and had 350 left in a buried lie, made bogey. The next I hooked left and made bogey, and the last I had 206, I thought the wind was into my face but it was all over the place, I couldn't have layed up unless I wanted to hit it 100 yards, I tried to hit a high cut 3 wood and it went straight and didn't get caught by the wind at all, managed to save par. So my question is how can I make more birdies, and when would be the best scenarios to attack in. I did have a bit of misfortune on the double bogey and a few other holes, but I still am not giving myself good chances.

Thanks
