Considering the relatively low speed of the crash there's a very good chance nothing needs to be replaced.

Install your front wheel and check its position, remove it and flip it around. If its in the same position your wheel is properly dished and the issues with the fork.

Forks with legs that are sweeped to the side or with 1 leg back are tough to eye up.

1. Align your front wheel with the top tube and measure the distance from the centerline of your skewer to the centerline of your BB or rear axle. A difference from left to right will tell you if a single leg is bend back in relation to the other.

2. If you know your wheel is properly dished dead on, install and check to see if its centered in the fork. While sitting on the bike if your wheel is canted left your fork need to bent to the right. Obviously if your wheel sits canted to the right your legs are bent to the left.

Hopefuly your not dealing with a combination of a side bend and a back bend.
