If you do not pray as a couple I encourage you to start. Here are some ways to do that:
Start by praying silently together. Sit down together and hold hands. Discuss your mutual concerns and start to pray silently. As you get more comfortable with silent prayer you can finish your silent prayer aloud by taking turns expressing thanksgiving and praise. You can also take this time to thank God for being present with you and hearing your prayer. Another way to pray is out loud together. Prayer does not have to take hours, but can be as simple as a few minutes a day that you set aside to invite the Lord into your marriage. You can pray for God to bless your marriage and also to protect it. Thank God for the things he is blessing you with. The goal is to pray together consistently.
