When you're on a breakaway, the easy way to score is to go on the right side of your player is a left handed shooter; go on the left if you're player is right handed. Then go towards the goalie at an angle, then deke backhand and quickly go forehand and shoot, 85% of the time it will go in. Another way if you have a player with bad handling; go straight towards the goalie and when you're about 1.5 meters near the goalie, quickly go to the forehand and press shoot at the same time, or move the analog stick to the forehand and rapidly press shoot button.
