Since 1983, Kayanan has illustrated for every major comic book publisher. His most notable work has been on Marvel Comics' Conan, Acclaim Comics' Turok and DC Comics' Firestorm. He also inked the Eisner-nominated series Chiaroscuro: The Life and Times of Leonardo Da Vinci for Vertigo Comics.
Kayanan has illustrated and developed concept designs for comic book, film and game companies. During the late 1990s, he was the creator and art director for Cross Plains Comics featuring the Pulp magazine characters created by Robert E. Howard. Kayanan developed concept designs for Nintendo's ground-breaking Turok: Dinosaur Hunter II video game. He currently continues to do work for Topps Cards on licenses such as Star Wars and The Lord of the Rings.
Kayanan's art is known for its rapid tempo, storytelling pace and layered depth. Much thought is evident in the choreography of dynamic action on every page. His slick and precise usage of shadows to define anatomy and emotion is as proficient as any of the longtime masters of the craft.
Kayanan is a Master-level edged weapons (knife, sword, tomahawk) expert and instructor in Sayoc Kali. This rare combination of a visual and martial artist, has led to projects which utilize both skills to illustrate fight storyboards for film and TV. Kayanan choreographed and trained the actors, in William Friedkin's The Hunted, starring Benicio del Toro and Tommy Lee Jones. He also trained actor Sam Rockwell for director George Clooney's film, Confessions of a Dangerous Mind. Kayanan was a development artist, fight trainer and weapons consultant for Paramount Pictures adaptation of Edgar Rice Burroughs' John Carter of Mars. His art was used for the hit CBS show NCIS: Los Angeles. Kayanan designed fights for the main cast of LL Cool J, Chris O' Donnell, Daniela Ruah and Eric Christian Olsen, as well as special guest stars Danny Trejo, Ernie Reyes, Jr.  and Daniel Henney. Kayanan was the technical advisor for the close quarter fights inside the airplane of the film Non-Stop starring Liam Neeson.
Additional comic book work can be found in issue 39 of Dark Horse Comics' Conan, Annihilation, and fantasy novelist R.A. Salvatore's Drizzt, Worlds of Dungeons & Dragons from Devil's Due Publishing.
Kayanan worked on concept illustration for the films Immortals. and Mirror, Mirror both directed by Tarsem Singh from Relativity Media, and the related graphic novel anthology Immortals: Gods and Heroes published by Archaia.
Recent projects include the Discovery TV show Lone Target, also known internationally as Manhunt, starring former Navy SEAL Joel Lambert where Kayanan designed RnD Hawk, Bontoc and Madumi Sayoc Kali-Daniel Winkler knives were prominently featured.
