My non-duality practices have been centered around knowledge (Jnana) and meditation (Raja). Devotion (Bhakti) has never been my strong suite, even going back to my Roman Catholic upbringing.
I've been at a loss how to work in Karma Yoga from a practical standpoint but my understanding was the main practice was one more aligned with seeing God in everything (devotion/Bhakti) so my enthusiasm for it just wasn't sufficient to make it a consistent and meaningful practice.
Lo and behold my favorite swami recently produced two excellent videos on it and one of the practices, Work as Witness, is Jnana-based and has synergy with my current practices. They are mutually reinforcing and I find it very seamless to be aware of this and practice throughout the day. Basically work/action is no work/action or in other words I am the Witness of the mind-body's work. It shifts the "I am" from the self of mind-body to the Self of awareness.

It's also said Karma Yoga is the foundational practice of Advaita spirituality, so better late than never. LOL!
