Another way to become more aware of your breath is to meditate. You can start with just 1 minute every morning to get started, and add a little more time each week. It's such a simple thing that can be done in any quiet space, I would even suggest it at your work desk if you are getting a bit frustrated or just want to come back to center.
There are plenty of apps out there to get you started. The one I'm familiar with is the Headspace app. It requires 10 minutes a day and encourages you to gradually build up your meditation practice. You'll begin to establish a habit of meditation with their foundational course, Take10, and can sign up for a monthly subscription thereafter if you prefer a voice guided meditation.
Meditation after a yoga practice is easier for me than just sitting down to meditate; my mind is already calm and meditation fits right in. Try it out if you find yourself antsy when you sit down to meditate.
Adaptation of a meditation from Gabrielle Bernstein's book, May Cause Miracles:
Take a deep breath in through your nose, and a long exhale out through your mouth. For your second breath think about breathing in joy and strength, then breath out wisdom and peace. Take 3 deep breaths like this and see if you feel any different afterwards.
