The reason I focused on labor-augmenting technology is that a balanced growth path requires technology to be represented in that form. Thus, generally TFP growth can be written as labor augmenting growth (usually due to the use of a Cobb-Douglas function).
Y_t=A_t K_t^\alpha N_t^{1-\alpha}=K_t^\alpha\left(A_t^{1/(1-\alpha)} N_t\right)^{1-\alpha}=K_t^\alpha\left(\tilde A_t N_t\right)^{1-\alpha}
