The module provides prev_step_link_text and next_step_link_text variables for this purpose:

localgov_step_by_step/localgov_step_by_step.module

Line 142 in 8a85f38

$variables['prev_step_link_text'] = t('Previous Step');

localgov_step_by_step/localgov_step_by_step.module

Line 147 in 8a85f38

$variables['next_step_link_text'] = $is_first_step ? t('Next Step') : t('Next Step');
