At least 20 people were injured as Morales supporters battled with police in the cities of La Paz and El Alto, local media report.
Mr Morales, 60, accused the police of targeting peaceful protesters and urged Bolivians to resist the “dark powers” that had forced him to resign.
Others have been celebrating his departure after nearly 14 years.
Mr Morales, Bolivia’s first indigenous leader, stepped down on Sunday after the head of the army publicly called on him to leave his post.
But he struck a defiant note on Twitter on Monday, saying that “the Bolivian people have never abandoned me and I will never abandon them”. He has also said that he was the victim of a “civic coup”.
