Would the Inuzuka or Nara technique count as a kekkei genkai?
Nope, they are not. The abilities that you mentioned are just hiden (秘伝, not to be confused with "hidden") techniques, exclusive to a specific clan. There is a difference between them and kekkei genkai abilities.

Kekkei Genkai is passed down genetically, so every member of a clan has an aptitude for it. 
The hiden techniques, on the contrary, are not passed down genetically, but rather "taught", so in fact anyone could learn them if they were not kept in secret. 

For example, take Parasitic Destruction Insect Technique, which is exclusive to Aburame clan. However, it's not a genetically-passed ability, it's rather that only Aburame clan knows what needs to be done in order to place the insects into one's body and to learn how to live in symbiosis with them.
